Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile IAB node provides service based on fixed base station specifications, then service provision can be established, but service continuity and efficiency deteriorate when the node moves outside specific areas
Solution Approach 1:
The patent applies dynamics by enabling the mobile IAB node to dynamically adjust its service provision behavior based on real-time position information and area-specific radio parameter settings. The node transitions from static service provision to dynamic adaptation, continuously monitoring its location and comparing radio parameters against stored area-specific configurations to determine whether to maintain or interrupt service.
Solution Approach 2:
The patent implements parameter changes by utilizing area-specific radio parameter settings stored in the mobile IAB node. When the node enters or exits specific areas, it compares current radio parameters with stored area-specific parameters and adjusts its service provision accordingly, changing operational parameters based on geographical location.
2Ease of operation
If the mobile IAB node interrupts service when moving outside specific areas, then area-specific service control is achieved, but service productivity deteriorates due to unnecessary interruptions
Solution Approach 1:
The patent implements feedback by establishing a closed-loop control mechanism where the mobile IAB node continuously monitors its position, compares current radio parameters with area-specific stored parameters, and adjusts service provision based on the comparison results. This feedback loop enables intelligent decision-making that prevents unnecessary service interruptions while maintaining area-specific control.
Solution Approach 2:
The patent applies self-service by enabling the mobile IAB node to autonomously determine whether to maintain or interrupt service based on its own position information and stored area-specific radio parameter settings. The node independently performs comparisons and makes service continuity decisions without external intervention, optimizing service delivery efficiency.
3Reliability
If the mobile IAB node continuously monitors position information, then service continuity is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by having the mobile IAB node monitor position information and compare radio parameters at specific intervals or when triggering events occur (such as entering or exiting defined areas). This periodic monitoring approach maintains service continuity while reducing energy consumption compared to continuous monitoring.
